Description of drawings
Other advantages of the present invention and characteristic show by following description, wherein with reference to the accompanying drawings embodiments of the invention are described in detail.Wherein show:
The sectional side elevation of Fig. 1 temperature sensor;
The equivalent circuit diagram that Fig. 2 is shown in Figure 1 for temperature sensor;
Fig. 3 describes the chart of the characteristic curve of temperature sensor shown in Figure 1; And
The block diagram of the another kind of temperature sensor of Fig. 4.
Embodiment
Fig. 1 shows temperature sensor 1, and it is set to be used to measure the temperature of waste gas.Temperature sensor 1 has the columniform housing 2 of longitudinal extension, on this housing the design have around stop collar 3.Stop collar 3 limits a stopper section, and the housing 2 of temperature sensor 1 can be inserted in the wall of exhaust piping till this stopper section.For this purpose, can design pipe adapter on exhaust piping, temperature sensor 1 is inserted in this pipe adapter, and temperature sensor 1 can for example be fixed in this pipe adapter by means of set nut.
Be provided with thermistor 4 (Thermistor) in the inside of housing 2, thermistor is resisted against on the bottom 5 of housing 2.Thermistor 4 is meant negative tempperature coefficient thermistor (Heissleiter) especially, and it is provided for measuring the high temperature in the scope that is up to 1100 ℃.Yet thermistor 4 also can be a platinum resistance.Thermistor 4 utilizes contact disc 6 to cover in a side relative with bottom 5, and contact disc is connected with contact pilotage 7.Contact pilotage 7 is surrounded by insulating sleeve 8.Therefore insulating sleeve 8 is resisted against on the inboard of housing 2, and with contact pilotage 7 and also contact disc 6 is remained on the approximate concentric position.When thermistor 4 was installed on the contact disc 6, insulating sleeve 8 also made thermistor 4 and housing 2 keep certain distance.
Because temperature sensor 1 is inserted in the exhaust piping till stop collar 3, portion's section that temperature that thermistor 4 and contact disc 6, contact pilotage 7 and insulating sleeve 8 are arranged in housing 2 has raise.Therefore, insulating sleeve 8 is preferably by the stupalith manufacturing.
The relative end of insulating sleeve 8 is provided with the detection resistance 9 that is designed to annular, and this detects resistance and is connected conductively with contact pilotage 7 by ring spring 10.Ring spring 10 is kept by contact disc 11.Contact disc 11 is connected with another contact pilotage 12.Contact pilotage 12 and contact disc 11 are kept by insulating sleeve 13, and this insulating sleeve for example is pressed against on the contact disc 11 and therefore by housing cover 14 and is pressed onto on the ring spring 10.Insulating sleeve 13 can be made by stupalith equally.Be not exposed under the high temperature of waste gas because insulating sleeve 13 is positioned at outside the exhaust piping and therefore, therefore can use other insulating material, for example plastics yet.Housing cover 14 also can replace with the fish platee (Laschen) of housing, and these fish platees are after the assembly that the inside that is positioned at housing 2 has been installed, on the insulating sleeve 13 that bends inwards.In addition, also can use volute spring and substitute ring spring 10.
In the zone of housing cover 14, also can be provided with and be used to the stationary installation 17 that connects the stationary installation 15 of shell cable (Massekabel) 16 and be used to connect signal cable 18.
Simple as much as possible for the installation that makes temperature sensor 1, be arranged on the inside of housing 2 parts, particularly thermistor 4, contact disc 6 and 11, contact pilotage 7 and 12 and ring spring 10 preferably be designed to rotational symmetric.In addition, insulating sleeve 8 is provided with and detects the recess of resistance 9 complementations.
For mounting temperature sensor 1, at first thermistor 4 is inserted in the housing 2 together with contact disc mounted thereto 6 and contact pilotage 7.And then insulating sleeve 8 is inserted.And then can will detect resistance 9 insertions and ring spring 10 be packed into.After inserting contact disc 11, contact pilotage 12 and insulating sleeve 13, can install housing cover 14.Respectively shell cable 16 and signal cable 18 are installed on stationary installation 15 and 17 at last.
Because it is concentric being inserted into the Component Design of the inside of housing 2, the installation of temperature sensor 1 can be implemented simply and can be undertaken by aut.eq. sometimes.
Because thermistor 4 directly is resisted against on the bottom 5 of housing 2, between thermistor 4 and the waste gas mobile, produced good thermal coupling around housing 2.Correspondingly, realized of short duration response time for temperature sensor 1.In addition, in housing 2, through hole needn't be had so that thermistor 4 and waste gas heat coupling.Therefore, if the soot particulate that is included in the waste gas is no longer taken away by waste gas stream, then they can only be deposited on the surface of housing 2.Therefore soot particulate just can not be attached to the inside of housing 2.
Another advantage of temperature sensor 1 is: the parts that are positioned at housing 2 inside are in spring force and compress down.The assembly that is positioned at housing 2 inside thus can be made fault-tolerantly.In addition, the too high welding position of cost is unnecessary.
Can detect operational situation by being integrated into detection resistance 9 in the temperature sensor 1 up to the lead-in wire that detects resistance 9.Fig. 2 shows the equivalent circuit diagram of temperature sensor 1, and wherein thermistor 4 becomes clear with being connected of controller 19.Controller 19 can for example be a truck-mounted computer.According to Fig. 2 as can be seen: by detect resistance 9 can check lead-in wire-be in the running of signal cable 18 and contact pilotage 12 and earth lead-be the short-circuit conditions in the running of housing 2 and shell cable 16.
Yet the characteristic curve of thermistor 4 changes by the existence that detects resistance 9.
Fig. 3 shows the chart of the characteristic curve of describing temperature sensor 1.Resistance variations curve 20 has showed the relation that depends on temperature of the resistance of thermistor 4.Resistance variations curve 20 is along with the temperature that descends is upwards soaring sharp.Another resistance variations curve 21 has represented that the resistance of temperature sensor 1 depends on the relation of temperature.Resistance variations curve 21 at first rises along with the temperature that descends, and then becomes mild corresponding to the resistance value that detects resistance 9.This value that detects resistance 9 is typically in the scope between 10k Ω and 20k Ω.
In the flexible program of the temperature sensor of describing according to Fig. 1 to Fig. 31, circuit carrier 22 can be set in the inside of housing 2, this circuit carrier is connected with thermistor 4 by contact wire 23.Contact wire 23 can design corresponding to contact disc 6 and contact pilotage 7.Can design sensor circuit on circuit carrier 22, these sensor circuits for example are used for signal Processing, and particularly signal amplifies.Particularly can produce digital measuring-signal, this measuring-signal sends on the controller 19 by data line 24.Particularly can when the transmission measurement signal, prevent from better thus to disturb.Can be with agreement, for example SAESENT is applied to data transmission.But data transmission also can be carried out by means of pulse-length modulation.In addition, the sensor circuit of design also can provide open collector output (Kollectorausgang) on circuit carrier 22.By the mode on the data-signal that for example DC component is added to, thereby make also and can keep power supply by data line 24 to sensor circuit.Also exist following possibility in addition: additional sensor is set, can utilizes this sensor for example to monitor temperature in the zone of circuit carrier 22 on circuit carrier 22.In this way, can identify circuit carrier 22 may occur overheated.At last, also thermistor 4 can be fixed on the circuit carrier 22 or disposed thereon.
It should be appreciated that at last except that data line 24, controller 19 also is connected with circuit carrier 22 by ground wire 25 (Masseleitung).
Should be noted in the discussion above that the odd number that uses has comprised plural situation in claim and instructions, unless context makes the certain situation difference.Particularly when having used indefinite article, not only represent odd number but also represent plural number.
To point out at last, also can combine in feature and the characteristic described in conjunction with the specific embodiments, unless this reason owing to compatibility is excluded with another embodiment.
